General Error: 1025 Error On Rename Of Laravel
Sign up Help with: ERROR 1025 (HY000): Error on rename of … (errno: 150) up vote 35 down vote favorite 7 I am getting this error when I am trying to run an alter table command to drop a column: ERROR 1025 (HY000): Error on rename of .... (errno: 150). If I understand correctly it is a foreign key problem, but I error code 1025 outlook mac do not have a clue how to fix it. Would somebody be so kind and tell me how to get it working. The code used for creating table: CREATE TABLE categories( cid INT AUTO_INCREMENT NOT NULL PRIMARY KEY, assets_id INT NOT NULL, cat_name VARCHAR(30) NOT NULL, INDEX(assets_id), FOREIGN KEY (assets_id) REFERENCES asset(aid) ON UPDATE CASCADE ) ENGINE=INNODB DEFAULT CHARSET=utf8; The alter command: ALTER TABLE categories DROP COLUMN assets_id; The table categories is completely blank. So there is no information to set off the CASCADE restrictions. So could you help me what kind of wizardry do I need to delete the column assets_id. Thank you. mysql share|improve this question edited May 10 '11 at 10:50 Manoj 3,43574364 asked May 10 '11 at 10:31 Henkka 3623817 add a comment| 3 Answers 3 active oldest votes up vote 66 down vote accepted Use SHOW CREATE TABLE categories to show the name of constraint. Most probably it will be categories_ibfk_1 Use the name to drop the foreign key first and the column then: ALTER TABLE categories DROP FOREIGN KEY categories_ibfk_1; ALTER TABLE categories DROP COLUMN assets_id; share|improve this an

Right now it has a primary key like this: PRIMARY KEY (user_id, round_number) Where user_id is a foreign key. I am trying to change it to this: PRIMARY KEY (user_id, round_number, created_at) I am doing this in phpmyadmin by clicking on the primary key icon in the table structure view. This is the error I get: #1025 - Error on rename of './database/#sql-2e0f_1254ba7' to './database/table' (errno: 150) It is a MySQL database with InnoDB table engine. http://stackoverflow.com/questions/4080611/1025-error-on-rename-of-database-sql-2e0f-1254ba7-to-database-table mysql sql phpmyadmin innodb mysql-error-1025 share|improve this question edited Apr 30 '11 at 17:29 OMG Ponies 199k37360417 asked Nov 2 '10 at 17:55 Richard Knop 23.6k95284462 1 A quick search using Google gives me the idea that this problem is related to constraints.

To find out which table caused the error you can run SHOW ENGINE INNODB STATUS and then look at the LATEST FOREIGN KEY ERROR section. share|improve this answer edited Nov 20 '14 at 11:00 trejder 6,5031366131 answered Nov 2 '10 at 18:50 Ike Walker 33.6k95278 add a comment| up vote 18 down vote For those who are getting to this question via google... this error can also happen if you try to rename a field that is acting as a foreign key. share|improve this answer answered Jun 20 '13 at 13:03 Dave C 267521 add a comment| up vote 18 down vote As was said you need to remove the FKs before. On Mysql do it like this: ALTER TABLE `table_name` DROP FOREIGN KEY `id_name_fk`; ALTER TABLE `table_name` DROP INDEX `id_name_fk`; share|improve this answer edited Sep 28 at 12:31 answered Sep 4 '13 at 21:04 Welli
